那些遇到过的问题

运行 Eureka Server 时无法启动嵌入式 Tomcat

med*_*ech 1 eclipse tomcat maven spring-boot netflix-eureka

我刚开始使用微服务，我想创建一个简单的 Eureka 服务器来执行我的 Serviceregistry。现在我只想在本地主机上运行服务器，稍后我想添加一个注册到它的示例微服务。问题是我在尝试启动 Eureka Server 时遇到错误。我在 Eclipse 中使用 Spring 和 Maven 在 ubuntu vm 中进行开发。

我的 POM.xml 如下所示：

我的 ErurekaServiceApplication 看起来像：

我发现这篇文章讨论了 JDK 9 及更高版本的 Tomcat 故障。导致缺少 JAXB 依赖项，这些依赖项已从 EE 版本的 JDK 中删除，并且仅存在于 JDK 8 及更低版本中。发生在Jersey （servlet 容器）上。

此修复应适用于其他 SpringBoot 组件：Zuul、Hystrix和Config Server。

完整指南：Spring Cloud Eureka 服务器/客户端

环境：

  • SpringBoot 2.1.8.RELEASE
  • Spring Cloud：Greenwich.SR2
  • JDK：11

请阅读文章并添加以下内容：

这就是我开始超越例外的原因。javax.xml.bind 的Java 11 包不再存在。
